Floquet Exponents and Bifurcations in Switched Converters

Switched power converters are finding wide applications in the area of electrical energy conditioning. Many electronic devices have power converters to achieve high conversion efficiency and therefore low heat waste. Some of them are: drivers for industrial motion control, battery chargers, uninterruptible power supplies (UPS), electric vehicles, laptops, gadgets and mobile phones. Therefore control of power converters in order to optimize conversion efficiency is a current and challenging research topic. Pulsewidth modulation (PWM) is the most used method to control power converters [11]-[12].
